Method Details

getTargetCharValueEscape

public Map<Character, String> getTargetCharValueEscape()

Description copied from class: Target

For pure strings of Unicode char, how can we display it in the target language as a literal. Useful for dumping predicates and such that may refer to chars that need to be escaped when represented as strings. Also, templates need to be escaped so that the target language can hold them as a string. Each target can have a different set in memory at same time.

Overrides:

getTargetCharValueEscape in class Target

getReservedWords

protected Set<String> getReservedWords()

Specified by:

getReservedWords in class Target

needsHeader

public boolean needsHeader()

Overrides:

needsHeader in class Target

shouldUseUnicodeEscapeForCodePointInDoubleQuotedString

protected boolean shouldUseUnicodeEscapeForCodePointInDoubleQuotedString(int codePoint)

Overrides:

shouldUseUnicodeEscapeForCodePointInDoubleQuotedString in class Target

getRecognizerFileName

public String getRecognizerFileName(boolean header)

Description copied from class: Target

Generate TParser.java and TLexer.java from T.g4 if combined, else just use T.java as output regardless of type.

Overrides:

getRecognizerFileName in class Target

getListenerFileName

public String getListenerFileName(boolean header)

Description copied from class: Target

A given grammar T, return the listener name such as TListener.java, if we're using the Java target.

Overrides:

getListenerFileName in class Target

getVisitorFileName

public String getVisitorFileName(boolean header)

Description copied from class: Target

A given grammar T, return the visitor name such as TVisitor.java, if we're using the Java target.

Overrides:

getBaseListenerFileName

public String getBaseListenerFileName(boolean header)

Description copied from class: Target

A given grammar T, return a blank listener implementation such as TBaseListener.java, if we're using the Java target.

Overrides:

getBaseVisitorFileName

public String getBaseVisitorFileName(boolean header)

Description copied from class: Target

A given grammar T, return a blank listener implementation such as TBaseListener.java, if we're using the Java target.

Overrides:
