Class GroovyClassLoader

:
  TODO: multi threaded compiling of the same class but with different roots

for compilation... T1 compiles A, which uses B, T2 compiles B... mark A and B as parsed and then synchronize compilation. Problems: How to synchronize? How to get error messages?

Field Summary
`Map` | `classCache`
`CompilerConfiguration` | `config`
`Boolean` | `recompile`
`GroovyResourceLoader` | `resourceLoader`
`int` | `scriptNameCounter`
`Map` | `sourceCache`

Constructor Summary
`GroovyClassLoader()` creates a GroovyClassLoader using the current Thread's context Class loader as parent.
`GroovyClassLoader(ClassLoader loader)` creates a GroovyClassLoader using the given ClassLoader as parent
`GroovyClassLoader(GroovyClassLoader parent)` creates a GroovyClassLoader using the given GroovyClassLoader as parent.
`GroovyClassLoader(ClassLoader parent, CompilerConfiguration config, boolean useConfigurationClasspath)` creates a GroovyClassLaoder.
`GroovyClassLoader(ClassLoader loader, CompilerConfiguration config)` creates a GroovyClassLoader using the given ClassLoader as parent.

Method Summary
`Class` | `defineClass(ClassNode classNode, String file)` Loads the given class node returning the implementation Class
`Class` | `defineClass(ClassNode classNode, String file, String newCodeBase)` Loads the given class node returning the implementation Class.
`Class` | `defineClass(String name, def bytecode, ProtectionDomain domain)` A helper method to allow bytecode to be loaded. spg changed name to defineClass to make it more consistent with other ClassLoader methods
`void` | `expandClassPath(List pathList, String base, String classpath, boolean isManifestClasspath)` expands the classpath
`String` | `generateScriptName()`
`def` | `getClassPath()` gets the currently used classpath.
`GroovyResourceLoader` | `getResourceLoader()`
`Class` | `parseClass(File file)` Parses the given file into a Java class capable of being run
`Class` | `parseClass(String text, String fileName)` Parses the given text into a Java class capable of being run
`Class` | `parseClass(String text)` Parses the given text into a Java class capable of being run

Constructor Detail

### GroovyClassLoader

    public GroovyClassLoader()

  creates a GroovyClassLoader using the current Thread's context Class loader as parent.

### GroovyClassLoader

    public GroovyClassLoader(ClassLoader loader)

  creates a GroovyClassLoader using the given ClassLoader as parent

### GroovyClassLoader

    public GroovyClassLoader(GroovyClassLoader parent)

  creates a GroovyClassLoader using the given GroovyClassLoader as parent. This loader will get the parent's CompilerConfiguration

### GroovyClassLoader

    public GroovyClassLoader(ClassLoader parent, CompilerConfiguration config, boolean useConfigurationClasspath)

  creates a GroovyClassLaoder.
  param:
    parent the parten class loader
  param:
    config the compiler configuration
  param:
    useConfigurationClasspath determines if the configurations classpath should be added

### GroovyClassLoader

    public GroovyClassLoader(ClassLoader loader, CompilerConfiguration config)

  creates a GroovyClassLoader using the given ClassLoader as parent.

Method Detail

### defineClass

    public Class defineClass(ClassNode classNode, String file)

  Loads the given class node returning the implementation Class
  param:
    classNode
  return:
    a class
  deprecated:

### defineClass

    public Class defineClass(ClassNode classNode, String file, String newCodeBase)

  Loads the given class node returning the implementation Class.

  WARNING: this compilation is not synchronized
  param:
    classNode
  return:
    a class

### defineClass

    Class defineClass(String name, def bytecode, ProtectionDomain domain)

  A helper method to allow bytecode to be loaded. spg changed name to defineClass to make it more consistent with other ClassLoader methods
  deprecated:

### expandClassPath

    void expandClassPath(List pathList, String base, String classpath, boolean isManifestClasspath)

  expands the classpath
  param:
    pathList an empty list that will contain the elements of the classpath
  param:
    classpath the classpath specified as a single string
  deprecated:

### generateScriptName

    public String generateScriptName()

### getClassPath

    def getClassPath()

  gets the currently used classpath.
  return:
    a String[] containing the file information of the urls
  see:
    #getURLs()

### getResourceLoader
