Constructor Detail

CleanUpRequirements

public CleanUpRequirements(boolean requiresAST,
                           boolean requiresFreshAST,
                           boolean requiresChangedRegions,
                           Map<String,String> compilerOptions)
Create a new instance

Parameters:
requiresAST - true if an AST is required
requiresFreshAST - true if a fresh AST is required
requiresChangedRegions - true if changed regions are required
compilerOptions - map of compiler options or null if no requirements
Method Detail

requiresAST

public boolean requiresAST()
Tells whether the clean up requires an AST.

Note: This should return false whenever possible because creating an AST is expensive.

Returns:
true if the context must provide an AST

requiresFreshAST

public boolean requiresFreshAST()
Tells whether a fresh AST, containing all the changes from previous clean ups, will be needed.

Returns:
true if the caller needs an up to date AST

getCompilerOptions

public Map<String,String> getCompilerOptions()
Required compiler options.

Returns:
the compiler options map or null if none

requiresChangedRegions

public boolean requiresChangedRegions()
Tells whether this clean up requires to be informed about changed regions. The changed regions are the regions which have been changed between the last save state of the compilation unit and its current state.

Has only an effect if the clean up is used as save action.

Note:: This should return false whenever possible because calculating the changed regions is expensive.

Returns:
true if the context must provide changed regions
