SimpleTwine(String str)

Method Summary

Object[]	__optUncall() Bare Twine is atomic (representable by a literal expression), and therefore, even though it's transparent, returns null.
void	__printOn(TextWriter out) Enabled: Prints using E list syntax
String	bare() Enabled: Explicitly gets the String part of the twine.
char	charAt(int index) Enabled: From the E language, this is identical to get/1.
SourceSpan	getOptSpan() Enabled: Gets the sourceSpan part of the twine, if it's there.
ConstList	getParts() Enabled: @return A list of AtomicTwines.
Object	getSecretArray() An array of my characters.
Object[]	getSpreadUncall() '__makeTwine fromString(myStr)'
(package private) Twine	infectOneToOne(String str)
boolean	isBare() Enabled: Is the bare string all the info there is?
(package private) ConstList	mergedParts(AtomicTwine other)
ConstList	run(int start, int bound) Enabled: Returns a Twine.
int	size() Enabled: How many entries are in the list?

Method Detail

getSpreadUncall

public Object[] getSpreadUncall()

'__makeTwine fromString(myStr)'

__optUncall

public Object[] __optUncall()

Bare Twine is atomic (representable by a literal expression), and therefore, even though it's transparent, returns null.

Overrides:

__optUncall in class ConstList

isBare

public boolean isBare()

Description copied from class: Twine

Enabled: Is the bare string all the info there is?

Specified by:

isBare in class Twine

run

public ConstList run(int start,
                     int bound)

Description copied from class: Twine

Enabled: Returns a Twine.

Specified by:

run in class Twine

mergedParts

ConstList mergedParts(AtomicTwine other)

Specified by:

mergedParts in class AtomicTwine

getOptSpan

public SourceSpan getOptSpan()

Description copied from class: Twine

Enabled: Gets the sourceSpan part of the twine, if it's there.

If this is an AtomicTwine, then, if the SourceSpan is there, it's as accurate as you're going to get. If this is a CompositeTwine, then, if the SourceSpan is there, it describes a span that includes all the individual spans. If a CompositeTwine returns null, there may still be SourceSpans on the atomic parts, but they couldn't all be summarized into one covering span.

Specified by:

getOptSpan in class Twine

__printOn

public void __printOn(TextWriter out)
               throws IOException

Description copied from class: ConstList

Enabled: Prints using E list syntax

Specified by:

__printOn in interface EPrintable

Overrides:

__printOn in class ConstList

IOException

charAt

public char charAt(int index)
            throws IndexOutOfBoundsException

Description copied from class: Twine

Enabled: From the E language, this is identical to get/1. But we provide it so the ELib programmer can avoid boxing the character.

Specified by:

charAt in class Twine

IndexOutOfBoundsException

See Also:

String.charAt(int)

size

public int size()

Description copied from class: EList

Enabled: How many entries are in the list?

Specified by:

size in class EList

bare

public String bare()

Description copied from class: Twine

Enabled: Explicitly gets the String part of the twine.

When using this call, this call itself will be the top level construct for breaking cycles. XXX where & what do we stabilize?

Specified by:

bare in class Twine

getParts

public ConstList getParts()

Description copied from class: Twine

Enabled: @return A list of AtomicTwines. An empty Twine returns the empty list.

Specified by:

getParts in class Twine

infectOneToOne

Twine infectOneToOne(String str)

Specified by:

infectOneToOne in class Twine

getSecretArray

public Object getSecretArray()

An array of my characters.

Specified by:

getSecretArray in interface ArrayedList

Returns:
