Member Function Documentation

◆ sizeInBytes()

size_t juce::CharPointer_ASCII::sizeInBytes ( ) const
inlinenoexcept

Returns the number of bytes that are used to represent this string.

This includes the terminating null character.

References length().

◆ getBytesRequiredFor()

template<class CharPointer >
static size_t juce::CharPointer_ASCII::getBytesRequiredFor ( const CharPointer  text)
inlinestaticnoexcept

Returns the number of bytes that would be needed to represent the given string in this encoding format.

The value returned does NOT include the terminating null character.

Definition at line 199 of file juce_CharPointer_ASCII.h.

◆ writeWithDestByteLimit()

template<typename CharPointer >
size_t juce::CharPointer_ASCII::writeWithDestByteLimit ( const CharPointer  src,
const size_t  maxDestBytes 
)
inlinenoexcept

Copies a source string to this pointer, advancing this pointer as it goes.

The maxDestBytes parameter specifies the maximum number of bytes that can be written to the destination buffer before stopping.

◆ writeWithCharLimit()

template<typename CharPointer >
void juce::CharPointer_ASCII::writeWithCharLimit ( const CharPointer  src,
const int  maxChars 
)
inlinenoexcept

Copies a source string to this pointer, advancing this pointer as it goes.

The maxChars parameter specifies the maximum number of characters that can be written to the destination buffer before stopping (including the terminating null).
