Method Detail

idealByteArrayLength

public static int idealByteArrayLength(int minSize)

Return the "ideal length" for a byte[] that must be at least the given number of elements in length. This takes into account the underlying allocation strategy.

Parameters:

minSize - the minimum length of the array

Returns:

the ideal length for the array

idealCharArrayLength

public static int idealCharArrayLength(int minSize)

Return the "ideal length" for a char[] that must be at least the given number of elements in length. This takes into account the underlying allocation strategy.

Parameters:

minSize - the minimum length of the array

Returns:

the ideal length for the array

idealShortArrayLength

public static int idealShortArrayLength(int minSize)

Return the "ideal length" for a short[] that must be at least the given number of elements in length. This takes into account the underlying allocation strategy.

Parameters:

minSize - the minimum length of the array

Returns:

the ideal length for the array

idealIntArrayLength

public static int idealIntArrayLength(int minSize)

Return the "ideal length" for an int[] that must be at least the given number of elements in length. This takes into account the underlying allocation strategy.

Parameters:

minSize - the minimum length of the array

Returns:

the ideal length for the array

idealLongArrayLength

public static int idealLongArrayLength(int minSize)

Return the "ideal length" for a long[] that must be at least the given number of elements in length. This takes into account the underlying allocation strategy.

Parameters:

minSize - the minimum length of the array

Returns:

the ideal length for the array

idealObjectArrayLength

public static int idealObjectArrayLength(int minSize)

Return the "ideal length" for an Object[] (or subclass thereof) that must be at least the given number of elements in length. This takes into account the underlying allocation strategy.

Parameters:

minSize - the minimum length of the array

Returns:

the ideal length for the array

lowerIdealByteArrayLength

public static int lowerIdealByteArrayLength(int minSize)

Return the portion of a byte[] of the specified size that would fit into an ideal-sized array.

Parameters:

minSize - the preferred length of the array

Returns:

the length for the array that would fit
