Method Detail

reflectionHashCode

public static int reflectionHashCode(ReflectionAwareComparable object)

append

public EfficientReflectionHashCode append(boolean value)

Append a hashCode for a boolean.

This adds 1 when true, and 0 when false to the hashCode.

This is in contrast to the standard java.lang.Boolean.hashCode handling, which computes a hashCode value of 1231 for java.lang.Boolean instances that represent true or 1237 for java.lang.Boolean instances that represent false.

This is in accordance with the Effective Java design.

Parameters:

value - the boolean to add to the hashCode

Returns:

this

append

public EfficientReflectionHashCode append(byte value)

Append a hashCode for a byte.

Parameters:

value - the byte to add to the hashCode

Returns:

this

append

public EfficientReflectionHashCode append(char value)

Append a hashCode for a char.

Parameters:

value - the char to add to the hashCode

Returns:

this

append

public EfficientReflectionHashCode append(double value)

Append a hashCode for a double.

Parameters:

value - the double to add to the hashCode

Returns:

this

append

public EfficientReflectionHashCode append(float value)

Append a hashCode for a float.

Parameters:

value - the float to add to the hashCode

Returns:

this

append

public EfficientReflectionHashCode append(int value)

Append a hashCode for an int.

Parameters:

value - the int to add to the hashCode

Returns:

this

append

public EfficientReflectionHashCode append(long value)

Append a hashCode for a long.

Parameters:

value - the long to add to the hashCode

Returns:

this

append

public EfficientReflectionHashCode append(Object object)

Append a hashCode for an Object.

Parameters:

object - the Object to add to the hashCode

Returns:

this

append

public EfficientReflectionHashCode append(short value)

Append a hashCode for a short.

Parameters:

value - the short to add to the hashCode

Returns:

this

build

public Integer build()

Returns the computed hashCode.

Specified by:

build in interface org.apache.commons.lang3.builder.Builder<Integer>

Returns:

hashCode based on the fields appended
