Constructor Details

JavaLanguage

public JavaLanguage()

Method Details

getLanguageName

public String getLanguageName()

Returns:

the name of the programming language. E.g. "Java".

getVariableNameThis

public String getVariableNameThis()

Returns:

the name for CodeVariableThis. E.g. "this" or "self".

getKeywordForVariable

public String getKeywordForVariable(CodeLocalVariable variable)

Parameters:

variable - the CodeLocalVariable.

Returns:

the keyword for the declaration (e.g. "let ", "final ", "var ", or "val ").

getKeywordForCategory

public String getKeywordForCategory(CodeTypeCategory category)

Parameters:

category - the CodeTypeCategory.

Returns:

the keyword for the given category to use in the source-code.

getStatementTerminator

public String getStatementTerminator()

Returns:

the String used as suffix to terminate a CodeAtomicStatement. E.g. ";".

getNamePattern

protected Pattern getNamePattern(CodeItemWithName item)

Specified by:

getNamePattern in class AbstractCodeLanguage

Parameters:

item - the item to verify. May be ignored if pattern and validation is independent of the item type.

Returns:

the Pattern that defines valid names.

getSimpleNamePatternForPackage

protected Pattern getSimpleNamePatternForPackage()

Specified by:

getSimpleNamePatternForPackage in class AbstractCodeLanguage

Returns:

the Pattern that defines valid CodePackage names.

getSimpleNamePatternForType

protected Pattern getSimpleNamePatternForType()

Specified by:

getSimpleNamePatternForType in class AbstractCodeLanguage

Returns:

the Pattern that defines valid names for CodeType and CodeFile.

isRevervedKeyword

protected boolean isRevervedKeyword(String name,
 CodeItem item)

Specified by:

isRevervedKeyword in class AbstractCodeLanguage

Parameters:

name - the name of the CodeItem to create.

item - the CodeItem to verify that defines the given name. Will most probably be ignored but a language may allow keywords in specific places and forbid in others.

Returns:

true if the given name is invalid (for the given CodeItem) because it is a reserved keyword.

getPackageFilename

public String getPackageFilename(CodePackage pkg)

Parameters:

pkg - the CodePackage to be read or write.

Returns:

the filename for the given CodePackage.

getFileFilename

public String getFileFilename(CodeFile file)

Parameters:

file - the CodeType to be read or write.

Returns:

the filename for the given CodeType.

get

public static JavaLanguage get()

Returns:

the singleton instance.
