## [Java] Class GenericsType

- org.codehaus.groovy.ast.GenericsType

- This class is used to describe generic type signatures for ClassNodes.

  See Also:
    ClassNode

- - ### Nested Class Summary

    Nested classes
    Modifiers | Name | Description
    --- | --- | ---
    `static class` | `GenericsType.GenericsTypeName` | Represents GenericsType name TODO In order to distinguish GenericsType with same name(See GROOVY-8409), we should add a property to keep the declaring class.

  - ### Field Summary

    Fields
    Modifiers | Name | Description
    --- | --- | ---
    `static GenericsType[]` | `EMPTY_ARRAY` |

  - ### Constructor Summary

    Constructors
    Constructor and description
    `GenericsType (ClassNode type, ClassNode[] upperBounds, ClassNode lowerBound)`
    `GenericsType (ClassNode basicType)`

  - ### Methods Summary

    `` | `ClassNode` | `getType()`
    `` | `ClassNode[]` | `getUpperBounds()`
    `` | `boolean` | `isCompatibleWith(ClassNode classNode)` Compares this generics type with the provided class node.
    `` | `boolean` | `isPlaceholder()`
    `` | `boolean` | `isResolved()`
    `` | `boolean` | `isWildcard()`
    `` | `void` | `setName(String name)`

  - ### Inherited Methods Summary

    Inherited Methods
    Methods inherited from class | Name
    --- | ---
    `class ASTNode` | `copyNodeMetaData, getColumnNumber, getLastColumnNumber, getLastLineNumber, getLineNumber, getMetaDataMap, getText, hashCode, setColumnNumber, setLastColumnNumber, setLastLineNumber, setLineNumber, setMetaDataMap, setSourcePosition, visit`

- - ### Field Detail

    - #### public static final GenericsType[] EMPTY_ARRAY

  - ### Constructor Detail

    - #### public GenericsType(ClassNode type, ClassNode[] upperBounds, ClassNode lowerBound)

    - #### public GenericsType(ClassNode basicType)

  - ### Method Detail

    - #### public ClassNode getLowerBound()

    - #### public String getName()

    - #### public ClassNode getType()

    - #### public ClassNode[] getUpperBounds()

    - #### public boolean isCompatibleWith(ClassNode classNode)

      Compares this generics type with the provided class node. If the provided class node is compatible with the generics specification, returns true. Otherwise, returns false. The check is complete, meaning that nested generics are also checked.

      Returns:
        if `classNode` is or is not compatible with this generics specification
