org.eclipse.jdt.core.dom.CatchClause
Catch clause AST node type.
```
 CatchClause: catch ( FormalParameter ) Block 
```
The FormalParameter is represented by a {@link SingleVariableDeclaration}.
@since 2.0 @noinstantiate This class is not intended to be instantiated by clients.
org.eclipse.php.internal.core.compiler.ast.nodes.CatchClause
Represents a catch clause (as part of a try statement)
```
e.g. catch (ClassName $e) { },
 
```
org.mozilla.javascript.ast.CatchClause
Node representing a catch-clause of a try-statement. Node type is {@link Token#CATCH}.
```
CatchClause : catch ( Identifier [if Expression] ) Block
```
