Method Detail

hasAtLeastOneAnnotation

public static boolean hasAtLeastOneAnnotation(org.codehaus.groovy.ast.ClassNode node,
                                              String... annotations)

Determine if a ClassNode has one or more of the specified annotations on the class or any of its methods. N.B. the type names are not normally fully qualified.

Parameters:

node - the class to examine

annotations - the annotations to look for

Returns:

true if at least one of the annotations is found, otherwise false

hasAtLeastOneAnnotation

public static boolean hasAtLeastOneAnnotation(org.codehaus.groovy.ast.AnnotatedNode node,
                                              String... annotations)

Determine if an AnnotatedNode has one or more of the specified annotations. N.B. the annotation type names are not normally fully qualified.

Parameters:

node - the node to examine

annotations - the annotations to look for

Returns:

true if at least one of the annotations is found, otherwise false

hasAtLeastOneFieldOrMethod

public static boolean hasAtLeastOneFieldOrMethod(org.codehaus.groovy.ast.ClassNode node,
                                                 String... types)

Determine if a ClassNode has one or more fields of the specified types or method returning one or more of the specified types. N.B. the type names are not normally fully qualified.

Parameters:

node - the class to examine

types - the types to look for

Returns:

true if at least one of the types is found, otherwise false

subclasses

public static boolean subclasses(org.codehaus.groovy.ast.ClassNode node,
                                 String... types)

Determine if a ClassNode subclasses any of the specified types N.B. the type names are not normally fully qualified.

Parameters:

node - the class to examine

types - the types that may have been sub-classed

Returns:

true if the class subclasses any of the specified types, otherwise false

hasAtLeastOneInterface

public static boolean hasAtLeastOneInterface(org.codehaus.groovy.ast.ClassNode classNode,
                                             String... types)

getClosure

public static org.codehaus.groovy.ast.expr.ClosureExpression getClosure(org.codehaus.groovy.ast.stmt.BlockStatement block,
                                                                        String name,
                                                                        boolean remove)

Extract a top-level name closure from inside this block if there is one, optionally removing it from the block at the same time.

Parameters:

block - a block statement (class definition)

name - the name to look for

remove - whether or not the extracted closure should be removed

Returns:

a beans Closure if one can be found, null otherwise
