Method Details
-
length
int length()Returns the number of components in this array.- Returns:
- the integer count of components in this array.
-
getValue
Returns an array component value.- Parameters:
index- the index of the component to retrieve- Returns:
- the
Valueat the given index. - Throws:
IndexOutOfBoundsException- ifindexis outside the range of this array, that is, if either of the following are true:index < 0 index >=length()
-
getValues
-
getValues
Returns a range of array components.- Parameters:
index- the index of the first component to retrievelength- the number of components to retrieve, or -1 to retrieve all components to the end of this array.- Returns:
- a list of
Valueobjects, one for each requested array component ordered by array index. When there are no elements in the specified range (e.g.lengthis zero) an empty list is returned - Throws:
IndexOutOfBoundsException- if the range specified withindexandlengthis not within the range of the array, that is, if either of the following are true:index < 0 index >or iflength()length != -1and either of the following are true:length < 0 index + length >length()
-
setValue
Replaces an array component with another value.Object values must be assignment compatible with the component type (This implies that the component type must be loaded through the declaring class's class loader). Primitive values must be either assignment compatible with the component type or must be convertible to the component type without loss of information. See JLS section 5.2 for more information on assignment compatibility.
- Parameters:
index- the index of the component to setvalue- the new value- Throws:
IndexOutOfBoundsException- ifindexis outside the range of this array, that is, if either of the following are true:index < 0 index >=length()InvalidTypeException- if the type ofvalueis not compatible with the declared type of array components.ClassNotLoadedException- if the array component type has not yet been loaded through the appropriate class loader.VMCannotBeModifiedException- if the VirtualMachine is read-only - seeVirtualMachine.canBeModified().- See Also:
-
setValues
Replaces all array components with other values. If the given list is larger in size than the array, the values at the end of the list are ignored.Object values must be assignment compatible with the element type (This implies that the component type must be loaded through the enclosing class's class loader). Primitive values must be either assignment compatible with the component type or must be convertible to the component type without loss of information. See JLS section 5.2 for more information on assignment compatibility.
- Parameters:
values- a list ofValueobjects to be placed in this array. Ifvalues.size()is less that the length of the array, the firstvalues.size()elements are set.- Throws:
InvalidTypeException- if any of the newvaluesis not compatible with the declared type of array components.ClassNotLoadedException- if the array component type has not yet been loaded through the appropriate class loader.VMCannotBeModifiedException- if the VirtualMachine is read-only - seeVirtualMachine.canBeModified().- See Also:
-
setValues
void setValues(int index, List<? extends Value> values, int srcIndex, int length) throws InvalidTypeException, ClassNotLoadedException Replaces a range of array components with other values.Object values must be assignment compatible with the component type (This implies that the component type must be loaded through the enclosing class's class loader). Primitive values must be either assignment compatible with the component type or must be convertible to the component type without loss of information. See JLS section 5.2 for more information on assignment compatibility.
- Parameters:
index- the index of the first component to set.values- a list ofValueobjects to be placed in this array.srcIndex- the index of the first source value to use.length- the number of components to set, or -1 to set all components to the end of this array or the end ofvalues(whichever comes first).- Throws:
InvalidTypeException- if any element ofvaluesis not compatible with the declared type of array components.IndexOutOfBoundsException- if the array range specified withindexandlengthis not within the range of the array, or if the source range specified withsrcIndexandlengthis not withinvalues, that is, if any of the following are true:index < 0 index >or iflength()srcIndex < 0 srcIndex > values.size()length != -1and any of the following are true:length < 0 index + length >length()srcIndex + length > values.size()VMCannotBeModifiedException- if the VirtualMachine is read-only - seeVirtualMachine.canBeModified().ClassNotLoadedException- See Also:
