LineIndexMapBuilder

package saker.build.thirdparty.saker.util

public class LineIndexMapBuilder implements Appendable

saker.build.thirdparty.saker.util.LineIndexMapBuilder

java.lang.Object

java.lang.Appendable

Class that creates a line index map based on the character data passed to it.

The class creates line index map the same way as StringUtils.getLineIndexMap(CharSequence), but doesn't require to have the whole character sequence to be accessible, character data can be written to it in sequence.

Use getIndexMap() to retrieve the line index map.

Constructors

public	LineIndexMapBuilder() Creates a new instance initialized to receive character data.
public	LineIndexMapBuilder(int estimatedlinecount) Crates a new builder with an estimated number of lines that the result will contain.

Methods

public LineIndexMapBuilder	append(char c) Appends the specified character to this `Appendable`.
public LineIndexMapBuilder	append(CharSequence data) Appends the specified character sequence to this `Appendable`.
public LineIndexMapBuilder	append(CharSequence csq, int start, int end) Appends a subsequence of the specified character sequence to this `Appendable`.
public LineIndexMapBuilder	append(char[] csq) Appends the argument characters to the index builder.
public LineIndexMapBuilder	append(char[] csq, int start, int end) Appends a range of characters from a given array to the index builder.
public int[]	getIndexMap() Gets the line index map that was built from the character data passed to this builder.

public LineIndexMapBuilder()

Creates a new instance initialized to receive character data.

public LineIndexMapBuilder(int estimatedlinecount) throws IllegalArgumentException

Crates a new builder with an estimated number of lines that the result will contain.

The passed line count is an estimate, the build will grow accordingly if more lines are encountered.

estimatedlinecountThe estimated line count.

IllegalArgumentExceptionIf the estimation is 0 or negative.

public LineIndexMapBuilder append(char c)

Overridden from: Appendable

Appends the specified character to this Appendable.

cThe character to append

A reference to this Appendable

public LineIndexMapBuilder append(CharSequence data)

Overridden from: Appendable

Appends the specified character sequence to this Appendable.

Depending on which class implements the character sequence csq, the entire sequence may not be appended. For instance, if csq is a CharBuffer then the subsequence to append is defined by the buffer's position and limit.

dataThe character sequence to append. If csq is null, then the four characters "null" are appended to this Appendable.

A reference to this Appendable

public LineIndexMapBuilder append(CharSequence csq, int start, int end)

Overridden from: Appendable

Appends a subsequence of the specified character sequence to this Appendable.

An invocation of this method of the form out.append(csq, start, end) when csq is not null, behaves in exactly the same way as the invocation

     out.append(csq.subSequence(start, end))

csqThe character sequence from which a subsequence will be appended. If csq is null, then characters will be appended as if csq contained the four characters "null".

startThe index of the first character in the subsequence

endThe index of the character following the last character in the subsequence

A reference to this Appendable

public LineIndexMapBuilder append(char[] csq)

Appends the argument characters to the index builder.

csqThe characters.

this

public LineIndexMapBuilder append(char[] csq, int start, int end) throws IndexOutOfBoundsException

Appends a range of characters from a given array to the index builder.

csqThe character array.

startThe starting index in the array. (inclusive)

endThe end index in the array. (exclusive)

this

IndexOutOfBoundsExceptionIf the range is out of the array's bounds.

public int[] getIndexMap()

Gets the line index map that was built from the character data passed to this builder.

The builder instance is reuseable. The builder is not reset by this call, so appending more data will continue building the same line index.

The line index map.
