Method Detail

getSchemaName

public String getSchemaName()

Enabled: The name of the language this is a Schema for, for diagnostic purposes only.

getOptTagForCode

public AstroTag getOptTagForCode(short tagCode)

Enabled: Returns the tag represented by this tag code in the grammar described by this schema, or null.

getTagForCode

public AstroTag getTagForCode(short tagCode)

Enabled: Returns the tag represented by this tag code in the grammar described by this schema, or throw an exception.

getOptTagForName

public AstroTag getOptTagForName(String tagName)

Enabled: Returns the tag represented by this tag name in the grammar described by this schema, or null if this schema doesn't define this tagName.

obtainTagForName

public AstroTag obtainTagForName(String tagName)

Enabled: Returns the tag represented by this tag name in the grammar described by this schema.

If there is no tag defined in this schema for this name, this still returns a (typically newly allocated) tag with this tagName and this schema, but with a tagCode of -1. Even in this case, the tagName of the resulting tag will be interned.

getLiteralCharTag

public AstroTag getLiteralCharTag()

Enabled: Gets the tag for representing character literals.

The literal data is canonically represented by a Character object.

getLiteralIntegerTag

public AstroTag getLiteralIntegerTag()

Enabled: Gets the tag for representing integer literals.

The literal data is canonically represented by a BigInteger object.

getLiteralFloat64Tag

public AstroTag getLiteralFloat64Tag()

Enabled: Gets the tag for representing floating point literals.

The literal data is canonically represented by a Double object.

getLiteralStringTag

public AstroTag getLiteralStringTag()

Enabled: Gets the tag for representing String literals.

The literal data is canonically represented by a Twine object.

getOptTypeTag

public AstroTag getOptTypeTag(Class clazz)

Enabled: Gets the tag for literally representing instances of clazz, or null if clazz is the wrong kind.

getTypeTag

public AstroTag getTypeTag(Class clazz)

Enabled: Gets the tag for literally representing instances of clazz, or throws if clazz is the wrong kind.
