Method Detail

isConstructor

boolean isConstructor()

Returns whether this method is a constructor.

Returns:

true for constructors, and false for methods

getReturnType

java.lang.String getReturnType()

Returns the return type name, or null. Returns null for constructors. The syntax for return type name corresponds to ReturnType in MethodDeclaration (JLS2 8.4). Names are returned as they appear in the source code; for example: "File", "java.io.File", "int[]", or "void".

Returns:

the return type

setReturnType

void setReturnType(java.lang.String type)

Sets the return type name. This has no effect on constructors. The syntax for return type name corresponds to ReturnType in MethodDeclaration (JLS2 8.4). Type names are specified as they appear in the source code; for example: "File", "java.io.File", "int[]", or "void".

Parameters:

type - the return type

getTypeParameters

java.lang.String[] getTypeParameters()

Returns the formal type parameters for this method. Returns an empty array if this method has no formal type parameters.

Formal type parameters are as they appear in the source code; for example: "X extends List<String> & Serializable".

Returns:

the formal type parameters of this method, in the order declared in the source, or an empty array if no type parameters are declared

setTypeParameters

void setTypeParameters(java.lang.String[] typeParameters)

Sets the formal type parameters for this method.

Parameters:

typeParameters - in the order declared in the source, or an empty array if no type parameters are declared

Since:

2.3.0

getParameterNames

java.lang.String[] getParameterNames()

Returns the names of parameters in this method in the order they are declared, or an empty array if no parameters are declared. The parameter names are identifiers as defined by Formal Parameters (JLS2 and JLS3 8.4.1). Parameter names do not include extra dimensions.

Returns:

the list of parameter names, or an empty array if no parameters are declared

getParameterTypes

java.lang.String[] getParameterTypes()

Returns the erased type names for the parameters of this method in the order they are declared, or an empty array if no parameters are declared. The syntax for type names is defined by Formal Parameters (JLS2 8.4.1). Type names must be specified as they would appear in source code. For example: "File", "java.io.File", or "int[]".

Returns:

the list of the erased types of the parameters, or an empty array if no parameters are declared

getFullParameterTypes

java.lang.String[] getFullParameterTypes()

Returns the full types for the parameters of this method in the order they are declared, or an empty array if no parameters are declared. The syntax for type names is defined by Formal Parameters (JLS2 8.4.1). Type names must be specified as they would appear in source code. For example: "File", "java.io.File", or "int[]".

Returns:

the list of the full types of the parameters, or an empty array if no parameters are declared

Since:

2.4

setParameterNames

void setParameterNames(java.lang.String[] names)
                throws java.lang.IllegalArgumentException

Sets the names of parameters in this method in the order they are to be declared. The parameter names are identifiers as defined by Formal Parameters (JLS2 and JLS3 8.4.1). Parameter names do not include extra dimensions.

Parameters:

names - the list of parameter names

Throws:

java.lang.IllegalArgumentException

getParameters

java.lang.String[] getParameters()

Returns the parameters of this method in the order they are declared, or empty array if no parameters are declared. The syntax for the parameters is defined by Formal Parameters (JLS2 and JLS3 8.4.1). Types and parameter names must be specified as they would appear in source code. For example: "File file", "java.io.File file", or "int[][] n[]", or final @Annotation int[]... n.

Returns:

the list of parameters, or or an empty array if no parameters are declared

Since:

2.3.0

setParameters

void setParameters(java.lang.String[] parameters)

Sets the parameters in this method in the order they are to be declared. The syntax for the parameters is defined by Formal Parameters (JLS2 and JLS3 8.4.1). Types and parameter names must be specified as they would appear in source code. For example: "File file", "java.io.File file", or "int[][] n[]", or final @Annotation int[]... n.

Parameters:

parameters - the list of parameters, or or an empty array if no parameters are declared

Since:

2.3.0

getExceptions

java.lang.String[] getExceptions()

Returns the type signatures of the exceptions this method throws, in the order declared in the source. Returns an empty array if this method throws no exceptions.

For example, a source method declaring "throws IOException", would return the array {"QIOException;"}.

The type signatures may be either unresolved (for source types) or resolved (for binary types), and either basic (for basic types) or rich (for parameterized types).

Returns:

the list of the exceptions, or an empty array if no exceptions are declared

setExceptions

void setExceptions(java.lang.String[] exceptionTypes)

Sets the names of the exception types this method throws, in the order in which they are declared in the source. An empty array indicates this method declares no exception types. The syntax for an exception type name is defined by Method Throws (JLS2 8.4.4). Type names must be specified as they would appear in source code. For example: "IOException" or "java.io.IOException".

Parameters:

exceptionTypes - the list of exception types

addException

void addException(java.lang.String exceptionType)

Adds the given exception to the end of the list of exceptions this method is declared to throw. The syntax for an exception type name is defined by Method Throws (JLS2 8.4.4). Type names must be specified as they would appear in source code. For example: "IOException" or "java.io.IOException". This is a convenience method for setExceptions.

Parameters:

exceptionType - the exception type

See Also:

setExceptions(String[])

getBody

java.lang.String getBody()

Returns the body of this method. The method body includes all code following the method declaration, including the enclosing braces.

Returns:

the body, or null if the method has no body (for example, for an abstract or native method)

setBody

void setBody(java.lang.String body)

Sets the body of this method. The method body includes all code following the method declaration, including the enclosing braces. No formatting or syntax checking is performed on the body.

Parameters:

body - the body, or null indicating the method has no body (for example, for an abstract or native method)
