Class Details

[line 33]
This class represents a text sample to be parsed.

This separates the analysis of a text sample from the primary LanguageDetect class. After a new profile has been built, the data can be retrieved using the accessor functions.

This class is intended to be used by the Text_LanguageDetect class, not end-users.

Method Detail

analyze [line 213]

void analyze(
)

Executes the parsing operation

Be sure to call the set*() functions to set options and the prepare*() functions first to tell it what kind of data to compute

Afterwards the get*() functions can be used to access the compiled information.

Access: public

getTrigramFreqs [line 186]

array &getTrigramFreqs(
)

Return the trigram freqency table

only used in testing to make sure the parser is working

Return: trigram freqencies in the text sample
Access: public

[ Top ]

getTrigramRanks [line 173]

array &getTrigramRanks(
)

Returns the trigram ranks for the text sample

Return: trigram ranks in the text sample
Access: public

[ Top ]

getUnicodeBlocks [line 197]

array &getUnicodeBlocks(
)

returns the array of unicode blocks

Return: unicode blocks in the text sample
Access: public

[ Top ]

prepareTrigram [line 129]

void prepareTrigram(
[bool
$bool = true])

turn on/off trigram counting

Access: public

Parameters:

bool $bool — true for on, false for off

[ Top ]

prepareUnicode [line 140]

void prepareUnicode(
[bool
$bool = true])

turn on/off unicode block counting

Access: public

Parameters:

bool $bool — true for on, false for off

[ Top ]

setPadStart [line 151]

void setPadStart(
[bool
$bool = true])

turn on/off padding the beginning of the sample string

Access: public

Parameters:

bool $bool — true for on, false for off

[ Top ]

setUnicodeSkipSymbols [line 162]

void setUnicodeSkipSymbols(
[bool
$bool = true])

Should the unicode block counter skip non-alphabetical ascii chars?

Access: public

Parameters:

bool $bool — true for on, false for off

[ Top ]

validateString [line 115]

bool validateString(
string
$str)

Returns true if a string is suitable for parsing

Return: true if acceptable, false if not
Access: public

Parameters:

string $str — input string to test
