setVerifying

public void setVerifying(boolean verifying)

isVerifyOnly

public boolean isVerifyOnly()

setVerifyOnly

public void setVerifyOnly(boolean verifyOnly)

getReturnType

public Class getReturnType()

setReturnType

public void setReturnType(Class returnType)

getParserContextState

public ParserContext getParserContextState()

isLiteralOnly

public boolean isLiteralOnly()
