Method Detail

getEnabled

public boolean getEnabled()

Description copied from interface: ResourceMinificationService

Indicates whether or not the system is allowed to minify bundled resources.

Specified by:

getEnabled in interface ResourceMinificationService

Returns:

the value of the system property "minify.enabled"

getAllowSingleMinification

public boolean getAllowSingleMinification()

Description copied from interface: ResourceMinificationService

Indicates whether or not the system is allowed to attempt to minify individual files. This can be useful if the YUI compressor is failing to minify JavaScript/CSS due to syntax errors and you are attempting to track down which file is problematic. It should not be enabled in a production environment.

Specified by:

getAllowSingleMinification in interface ResourceMinificationService

Returns:

the value of the system property "minify.allowSingleMinification"

minify

public byte[] minify(String filename,
            byte[] bytes)

Description copied from interface: ResourceMinificationService

Given the source byte[], will return a byte[] that represents the YUI-compressor minified version of the byte[]. The behavior of this method is controlled via the following properties:

• minify.enabled - whether or not to actually perform minification
• minify.linebreak - if set to a value other than -1, will enforce a linebreak at that value
• minify.munge - if true, will replace variable names with shorter versions
• minify.verbose - if true, will display extra logging information to the console
• minify.preserveAllSemiColons - if true, will never remove semi-colons, even if two in a row exist
• minify.disableOptimizations - if true, will disable some micro-optimizations that are performed

Specified by:

minify in interface ResourceMinificationService

Returns:

the minified bytes
