Method Detail

getItemMeta

ItemMeta getItemMeta(Material material)

This creates a new item meta for the material.

Parameters:

material - The material to consider as base for the meta

Returns:

a new ItemMeta that could be applied to an item stack of the specified material

isApplicable

boolean isApplicable(ItemMeta meta,
                     ItemStack stack)
              throws IllegalArgumentException

This method checks the item meta to confirm that it is applicable (no data lost if applied) to the specified ItemStack.

A SkullMeta would not be valid for a sword, but a normal ItemMeta from an enchanted dirt block would.

Parameters:

meta - Meta to check

stack - Item that meta will be applied to

Returns:

true if the meta can be applied without losing data, false otherwise

Throws:

IllegalArgumentException - if the meta was not created by this factory

isApplicable

boolean isApplicable(ItemMeta meta,
                     Material material)
              throws IllegalArgumentException

This method checks the item meta to confirm that it is applicable (no data lost if applied) to the specified Material.

A SkullMeta would not be valid for a sword, but a normal ItemMeta from an enchanted dirt block would.

Parameters:

meta - Meta to check

material - Material that meta will be applied to

Returns:

true if the meta can be applied without losing data, false otherwise

Throws:

IllegalArgumentException - if the meta was not created by this factory

equals

boolean equals(ItemMeta meta1,
               ItemMeta meta2)
        throws IllegalArgumentException

This method is used to compare two item meta data objects.

Parameters:

meta1 - First meta to compare, and may be null to indicate no data

meta2 - Second meta to compare, and may be null to indicate no data

Returns:

false if one of the meta has data the other does not, otherwise true

Throws:

IllegalArgumentException - if either meta was not created by this factory

asMetaFor

ItemMeta asMetaFor(ItemMeta meta,
                   ItemStack stack)
            throws IllegalArgumentException

Returns an appropriate item meta for the specified stack.

The item meta returned will always be a valid meta for a given ItemStack of the specified material. It may be a more or less specific meta, and could also be the same meta or meta type as the parameter. The item meta returned will also always be the most appropriate meta.

Example, if a SkullMeta is being applied to a book, this method would return a BookMeta containing all information in the specified meta that is applicable to an ItemMeta, the highest common interface.

Parameters:

meta - the meta to convert

stack - the stack to convert the meta for

Returns:

An appropriate item meta for the specified item stack. No guarantees are made as to if a copy is returned. This will be null for a stack of air.

Throws:

IllegalArgumentException - if the specified meta was not created by this factory
