Defined in namespace Smalltalk

Category: Language-Data types

My instances represent ASCII string data types. Being a very common case, they are particularly optimized.

6.133.1 String class: basic

, aString

Answer a new instance of an ArrayedCollection containing all the elements in the receiver, followed by all the elements in aSequenceableCollection

6.133.2 String class: instance creation

fromCData: aCObject size: anInteger

Answer a String containing anInteger bytes starting at the location pointed to by aCObject

6.133.3 String: built ins

asCData: aCType

Convert the receiver to a CObject with the given type

at: index

Answer the index-th character of the receiver.

at: index put: value

Change the index-th character of the receiver.

basicAt: index

Answer the index-th character of the receiver. This method must not be overridden; override at: instead. String overrides it so that it looks like it contains character objects even though it contains bytes

basicAt: index put: value

Change the index-th character of the receiver. This method must not be overridden; override at: instead. String overrides it so that it looks like it contains character objects even though it contains bytes

hash

Answer an hash value for the receiver

primReplaceFrom: start to: stop with: replacementString

startingAt: replaceStart Private - Replace the characters from start to stop with new characters contained in replacementString (which, actually, can be any variable byte class, starting at the replaceStart location of replacementString

replaceFrom: start to: stop with: aString startingAt: replaceStart

Replace the characters from start to stop with new characters whose ASCII codes are contained in aString, starting at the replaceStart location of aString

replaceFrom: start to: stop withByteArray: byteArray startingAt: replaceStart

Replace the characters from start to stop with new characters whose ASCII codes are contained in byteArray, starting at the replaceStart location of byteArray

size

Answer the size of the receiver

6.133.4 String: converting

asByteArray

Return the receiver, converted to a ByteArray of ASCII values

asString

But I already am a String! Really!

asSymbol

Returns the symbol corresponding to the receiver

6.133.5 String: storing

storeOn: aStream

Print Smalltalk code compiling to the receiver on aStream

6.133.6 String: testing functionality

isString

Answer `true'.

6.133.7 String: useful functionality

linesDo: aBlock

Send 'aBlock' a substring of the receiver for each newline delimited line in the receiver
