Method Detail

createWrapperList

public static IList<?> createWrapperList(java.lang.Class<?> type)

Create a GapList wrapping a primitive GapList, e.g. an IntObjGapList wrapping an IntGapList.

Parameters:

type - primitive type for GapList

Returns:

created wrapping GapList

Throws:

java.lang.IllegalArgumentException - if no primitive type is specified

createWrapperList

public static IList<?> createWrapperList(java.lang.Class<?> type,
                                         int capacity)

Create a GapList wrapping a primitive GapList, e.g. an IntObjGapList wrapping an IntGapList.

Parameters:

type - primitive type for GapList

capacity - initial capacity of created list

Returns:

created wrapping GapList

Throws:

java.lang.IllegalArgumentException - if no primitive type is specified

toGapList

public static <T> java.util.stream.Collector<T,?,GapList<T>> toGapList()

Return collector which collects the elements into a GapList.

Returns:

collector

toBigList

public static <T> java.util.stream.Collector<T,?,BigList<T>> toBigList()

Return collector which collects the elements into a BigList.

Returns:

collector

read

public static int read(java.io.InputStream istream,
                       org.magicwerk.brownies.collections.primitive.ByteGapList list,
                       int len)
                throws java.io.IOException

Read specified number of bytes from InputStream into ByteGapList.

Parameters:

istream - input stream (source)

list - list (target)

len - maximum number of bytes to read

Returns:

number of bytes read into the buffer, -1 if end of stream has been reached

Throws:

java.io.IOException

read

public static int read(java.io.Reader reader,
                       org.magicwerk.brownies.collections.primitive.CharGapList list,
                       int len)
                throws java.io.IOException

Read specified number of chars from Reader into CharGapList.

Parameters:

reader - reader (source)

list - list (target)

len - maximum number of bytes to read

Returns:

number of bytes read into the buffer, -1 if end of stream has been reached

Throws:

java.io.IOException

add

public static void add(java.lang.CharSequence str,
                       org.magicwerk.brownies.collections.primitive.CharGapList list,
                       int start,
                       int end)

Add specified number of chars from CharSequence into CharGapList.

Parameters:

str - CharSequence (source)

list - list (target)

start - start position of characters to add in CharSequence

end - end position of characters to add in CharSequence
