getAt

public Scalar getAt(Scalar key)

Description copied from interface: ScalarHash

Retrieves a scalar from the hashtable. If a scalar key does not exist then the key should be created with a value of $null. This $null or empty scalar value should be returned by the function. This is how values are added to Scalar hashes.

Specified by:

getData

public java.util.Map getData()

Description copied from interface: ScalarHash

Return the data structure backing this hash please

Specified by:

keys

public ScalarArray keys()

Description copied from interface: ScalarHash

Returns all of the keys within the scalar hash. If a key has a $null (aka empty scalar) value the key should be removed from the scalar hash.

Specified by:

Description copied from interface: ScalarHash

Removes the specified scalar from the hashmap. :)
