Method Detail

getVersion

public java.lang.String getVersion()

Description copied from class: Target

ANTLR tool should check output templates / target are compatible with tool code generation. For now, a simple string match used on x.y of x.y.z scheme. We use a method to avoid mismatches between a template called VERSION. This value is checked against Tool.VERSION during load of templates. This additional method forces all targets 4.3 and beyond to add this method.

Specified by:

getVersion in class Target

getBadWords

public java.util.Set<java.lang.String> getBadWords()

addBadWords

protected void addBadWords()

getSerializedATNSegmentLimit

public int getSerializedATNSegmentLimit()

Description copied from class: Target

Gets the maximum number of 16-bit unsigned integers that can be encoded in a single segment of the serialized ATN.

Overrides:

getSerializedATNSegmentLimit in class Target

Returns:

the serialized ATN segment limit
