public final class ScriptMetadata
extends Object

Metadata container for compiled Groovy scripts with hash-based change detection.

This class encapsulates all metadata associated with a compiled Groovy script, including content hash for efficient change detection and the compiled class for direct execution without recompilation.

Constructs a new ScriptMetadata instance.

Parameters:

actionName - the unique name/identifier of the action

scriptContent - the raw Groovy script content

compiledClass - the compiled Groovy script class

Throws:

IllegalArgumentException - if any parameter is null

Method Detail

hasChanged

public boolean hasChanged(String newContent)

Determines if the script content has changed compared to new content.

This method uses SHA-256 hash comparison for efficient change detection without storing or comparing the full script content.

Parameters:

newContent - the new script content to compare against

Returns:

true if content has changed, false if unchanged

Throws:

IllegalArgumentException - if newContent is null

getActionName

public String getActionName()

Returns the action name/identifier.

Returns:

the action name, never null

getScriptContent

public String getScriptContent()

Returns the original script content.

Returns:

the script content, never null

getContentHash

public String getContentHash()

Returns the SHA-256 hash of the script content.

Returns:

Base64 encoded content hash, never null

getCreationTime

public long getCreationTime()

Returns the timestamp when this metadata was created.

Returns:

creation timestamp in milliseconds since epoch

getCompiledClass

public Class<? extends groovy.lang.Script> getCompiledClass()

Returns the compiled Groovy script class.

This class can be used to create new script instances for execution without requiring recompilation.

Returns:

the compiled script class, never null
