Method Detail |
---|
public static StorageModel primitive(Class cl)
type.class
e.g. int.class
or referring to the static
constants of their counterpart reference type classes,
e.g. Integer.TYPE
.
cl
- the primitive type's class representation
public static StorageModel objectType(Class cl)
public StorageModel inlined(int numPerEntry)
*numPerEntry
.
Can be applied several times, e.g.
StorageModel.DOUBLE_ARRAY.inline(4).inline(4)
creates
a storage model for a list of 4x4 matrices still stored in
a linear double[]
array. Can also be used
in combination with array(int)
.
public StorageModel array(int numPerEntry)
StorageModel.INT_ARRAY.inline(2).inline(3)
creates
a storage model for a list of int[2][3]
entries.
Can also used combined with inlined(int)
.
array()
public StorageModel array()
array(int)
but without specifying an entry size.
Implies that entries might have different lengths. The resulting
storage model will return -1 if queried for the general entry
size.
public final DataList createReadOnly(Object v)
createReadOnly(Object,int,int)
assuming
offset 0
and the entire array length.
public DataList createReadOnly(Object v, int start, int length)
data list
using this data model.
Certain storage models will return specialized data lists,
e.g. DoubleArray
or IntArray
.
v
- the object to wrapstart
- start offset inside vlength
- the number of itemspublic WritableDataList createWritableDataList(Object v)
public String toString()
toString
in class Object
public abstract int getLength(Object data)
public int getNumberOfDimensions()
public int[] getDimensions()
-1
for list/array types as the is the length of the list.
getDimensions(DataList)
public int[] getDimensions(DataList from)
getDimensions()
but with initialization of the
first entry with the length of the specified list.
public boolean isArray()
public StorageModel getComponentModel()
public IntArray getAsIntArray(Object data, int index)
public DoubleArray getAsDoubleArray(Object data, int index)
