A base class for A.DateParser.

Constructor

A.DateParser

(
  • opt_pattern
)

Parameters:

  • opt_pattern String

    Mask as strftime string.

Methods

_expandPattern

(
  • pattern
  • pos
)
String protected

Expands the so called "aggregates" from the strftime pattern, e.g. %X represents expanded %Hh%Mmin%Ss pattern.

Parameters:

  • pattern String

    Mask as strftime string.

  • pos Array

    One position array that holds the text position number. An array instance is used to keep reference to the position counter, therefore can be passed to different subparse methods.

Returns:

String:

Expanded pattern.

_findBestStringMatch

(
  • val
  • data
  • opt_inverse
)
Number protected

Attempts to match the text at a given position against an array of strings. The longer match is classified as best match, e.g if the data array contains ["f", "fo", "foo", ...] all positions will match "foobar". The longest match is "foobar".

Parameters:

  • val String

    Keyword The string to match to.

  • data Array

    The string array of matching patterns.

  • opt_inverse Boolean

    Inverts the matching test. Instead of test array values against val, tests val against the array values.

Returns:

Number:

Best match index. Returns -1 if doesn't find any match.

_findNextSeparatorPos

(
  • compiled
  • compiledPos
  • text
  • Current
)
Number protected

Looks for the position of the next separator that is included in the text.

Parameters:

  • compiled Array

    Information about the compiled mask

  • compiledPos Number

    Current position in the compiled array

  • text String

    The text that is being parsed

  • Current Number

    position in the text being parsed

Returns:

Number:

Position of the next separator in the compiled array

_getCalendarDate

(
  • data
  • opt_date
)
Date protected

Based on the fields set, fill a Date object. For those fields that not set, use the passed in date object's value.

Parameters:

  • data Array

    The string array of matching patterns.

  • opt_date Date

    Date object to be filled.

Returns:

Date:

Filled date object. Returns false if have nothing to fill.

_getLangResource

(
  • token
)
Object protected

Gets resource object with tokens information for the loaded language.

Parameters:

  • token String

    Strftime token.

Returns:

Object:

Resource object.

_getNextNumericValue

(
  • text
  • textPos
)
String protected

Infer the next numeric value based on textPos position.

Parameters:

  • text String

    Input text.

  • textPos Array

    One position array that holds the text position number. An array instance is used to keep reference to the position counter, therefore can be passed to different subparse methods.

Returns:

String:

Inferred next value.

_getNextValue

(
  • text
  • textPos
  • opt_separator
  • opt_numeric
)
String protected

Infer the next value based on textPos position.

Parameters:

  • text String

    Input text.

  • textPos Array

    One position array that holds the text position number. An array instance is used to keep reference to the position counter, therefore can be passed to different subparse methods.

  • opt_separator String

    If specified is used as boundary of the next value.

  • opt_numeric Boolean

    If specified, find only next numeric values.

Returns:

String:

Inferred next value.

_getPatternHints

(
  • token
)
Object protected

Based on the strftime token, finds the hints object. Hints objects contains information such as size, numeric tokens and setters.

Parameters:

  • token String

    Strftime token.

Returns:

Object:

Hints object. If token is not supported returns false.

_subparseNumericBlob

(
  • blob
  • textPos
  • i
)
String protected

Sub-parses a numeric value. Some tokens are used in sequence, e.g. %d%m, resulting in ambigous values such as "20122013", for 12/20/2013. The found ambigous values are tested against the available token information in order to be separated.

Parameters:

  • blob String

    Ambigous numeric value.

  • textPos Array

    One position array that holds the text position number. An array instance is used to keep reference to the position counter, therefore can be passed to different subparse methods.

  • i Number

    Token position on the compiled array.

Returns:

String:

Non-ambiguous numeric value.

_subparseStringBlob

(
  • blob
  • textPos
  • i
)
String protected

Sub-parses a string value. Some tokens are used in sequence, e.g. %a%b, resulting in ambigous values such as "MonJun". The found ambigous values are tested against the available token values in order to be separated.

Parameters:

  • blob String

    Ambigous string value.

  • textPos Array

    One position array that holds the text position number. An array instance is used to keep reference to the position counter, therefore can be passed to different subparse methods.

  • i Number

    Token position on the compiled array.

Returns:

String:

Non-ambiguous string value.

_subparseTimeZone

(
  • text
  • textPos
  • i
)
Object protected

Sub-parses timezones.

Parameters:

  • text String

    Input text.

  • textPos Array

    One position array that holds the text position number. An array instance is used to keep reference to the position counter, therefore can be passed to different subparse methods.

  • i Number

    Token position on the compiled array.

Returns:

Object:

Found timezone.

compilePattern

(
  • pattern
)

"Compiles" the strftime pattern. The same DateParser instance can be reused to other "compiled" masks.

Parameters:

  • pattern String

    Mask as strftime string.

parse

(
  • mask
  • text
  • opt_date
)

  • opt_date Date

    Optional Date object to be used a base date for filling the parsed values.

    parse {HTML} (Optional)

    Any strftime string is supported, such as %I:%M:%S %p. This format has several specifiers defined by the Open group at: http://www.opengroup.org/onlinepubs/007908799/xsh/strftime.html

    PHP added a few of its own, defined at: http://www.php.net/strftime
