      oracle.javatools.editor.language.GenericBraceProvider

All Implemented Interfaces:

BraceProvider

public class GenericBraceProvider
extends AbstractBraceProvider
implements BraceProvider

The GenericBraceProvider implementation provides brace matching support for "generic" languages that implement the generic Language API to describe the language.

Constructor Detail

GenericBraceProvider

public GenericBraceProvider(LanguageSupport support,
                            Language language)

Constructs a new GenericBraceProvider associated with the given LanguageSupport and language instance. This will create a default GenericLexer instance to use.

Parameters:

support - the language support

language - the language definition

GenericBraceProvider

public GenericBraceProvider(LanguageSupport support,
                            Language language,
                            GenericLexer lexerToUse)

Constructs a new GenericBraceProvider associated with the given LanguageSupport and language instance. This allows a given language implementation to use a modified GenericLexer implementation.

Parameters:

support - the language support

language - the language definition

lexerToUse - the lexer to use
