Class StrTerm

java.lang.Object
  org.jrubyparser.lexer.StrTerm

Direct Known Subclasses:

HeredocTerm, StringTerm

public abstract class StrTerm
extends Object

Field Summary

protected int

processingEmbedded Flag set while we're processing embedded Ruby expressions.

Constructor Summary

StrTerm()

Method Summary

abstract Object	getMutableState() Record any mutable state from this StrTerm such that it can be set back to this exact state through a call to setMutableState(java.lang.Object) later on.
abstract boolean	isSubstituting() Report whether this string should be substituting things like \n into newlines (double quoting rules).
abstract int	parseString(Lexer lexer, LexerSource src)
abstract void	setMutableState(Object o) Support for incremental lexing: set current state of the term.
abstract void	splitEmbeddedTokens() Tell this string term to return separate tokens for embedded ruby code (#$foo, #@foo, #{foo})

Field Detail

processingEmbedded

protected int processingEmbedded

Flag set while we're processing embedded Ruby expressions. It will be 0 when we are not, or otherwise set to the the relevant embedded type (EMBEDDED_DVAR or EMBEDDED_DEXPR)

Constructor Detail

StrTerm

public StrTerm()

Method Detail

parseString

public abstract int parseString(Lexer lexer,
                                LexerSource src)
                         throws IOException

Throws:

IOException

splitEmbeddedTokens

public abstract void splitEmbeddedTokens()

Tell this string term to return separate tokens for embedded ruby code (#$foo, #@foo, #{foo})

isSubstituting

public abstract boolean isSubstituting()

Report whether this string should be substituting things like \n into newlines (double quoting rules). E.g. are we dealing with a "" string or a '' string (or their alternate representations)

getMutableState

public abstract Object getMutableState()

Record any mutable state from this StrTerm such that it can be set back to this exact state through a call to setMutableState(java.lang.Object) later on. Necessary for incremental lexing where we may restart lexing parts of a string (since they can be split up due to Ruby embedding like "Evaluated by Ruby: #{foo}".

setMutableState

public abstract void setMutableState(Object o)

Support for incremental lexing: set current state of the term. See getMutableState()
