Method Details

isFeatureSupportedinAST

public static boolean isFeatureSupportedinAST(AST ast,
 int featureName)

Validates if the given apiLevel and previewEnabled supports the provided nodeType. This API checks for node types supported from JLS 14 onwards and will return true> for nodes added before JLS14.

Parameters:

ast - the AST to be evaluated

featureName - the feature name constant indicating the feature to be evaluated

Returns:

true if the given AST supports the provided nodeType else false

Since:

3.22

See Also:

• ASTNode.getNodeType()

isFeatureSupportedinAST

public static boolean isFeatureSupportedinAST(int apiLevel,
 boolean previewEnabled,
 int featureName)

Validates if the given apiLevel and previewEnabled supports the provided nodeType. This API checks for node types supported from JLS 14 onwards and will return true> for nodes added before JLS14.

Parameters:

apiLevel - the level to be checked

previewEnabled - the preview feature to be considered

featureName - the feature name constant indicating the feature to be evaluated

Returns:

true if the given AST supports the provided nodeType else false

Since:

3.22

See Also:

• ASTNode.getNodeType()

isFeatureSupportedinAST

public static boolean isFeatureSupportedinAST(int apiLevel,
 int featureName)

Validates if the given apiLevel and previewEnabled supports the provided nodeType. This API checks for node types supported from JLS 14 onwards and will return true> for nodes added before JLS14.

Parameters:

apiLevel - the level to be checked

featureName - the feature name constant indicating the feature to be evaluated

Returns:

true if the given AST supports the provided nodeType else false

Since:

3.27

checkASTLevel

public static void checkASTLevel(int level)

getCompliance

public static String getCompliance(int astLevel)

Calculates the JavaCore Option value string corresponding to the input ast level. AST Level 4 is used for Java versions 1.4 to 1.7 and is converted to compliance level 7 if input ast level is out of boundary, latest compliance will be returned

Returns:

JavaCore Option value string corresponding to the ast level
